摘要

矿石开采过程中的泥浆冲击机制尚未得到充分研究。在这项研究中，建立了一个新的实验装置来分析受控条件下的泥涌事件。对一个块体崩落式抽矿钟进行了缩放，并用待提取的湿颗粒材料填充。然后根据其稠度指数对绘制的材料进行分类。结果表明，屈服应力和材料稠度是实验结果中泥浆事件的良好预测因素。最后，冲泥事件主要发生在材料稠度分为塑性、软性或流体时，其中软性和流体最为显著。

Experimental study of mudrush mechanisms under different moisture contents in block caving

ABSTRACT Mud-rush mechanisms during ore extraction have not been fully studied. In this study, a new experimental setup was created to analyse mud-rush events under controlled conditions. A block caving drawbell was scaled and filled with wet granular material to be extracted. The material drawn was then classified based on its consistency index. The results showed that the yield stress and the material consistency are good predictors of mud events in the experimental results. Finally, mud-rush events occurred mainly when material consistency was classified as plastic, soft, or fluid – with soft and fluid being the most significant.
